“…Thus the efficiency is improved and the torque values increased along the angular positions. To increase the power coefficient of Savonius turbine, Al-Kayiem et al [13] proposed installing a curtain in upstream flow of turbine and the rotor without shaft. By these configurations, the coefficient of power increase significantly.…”

Renewable sources of energy, abundant in availability, are needed to be exploited with adaptable technology. For wind energy, the wind turbine is very well adapted to generate electricity. Among the different typologies, small scale Vertical Axis Wind Turbines (VAWT) present the greatest potential for off-grid power generation at low wind speeds. The combined Darrieus-Savonius wind turbine is intended to enhance the performance of the Darrieus rotor in low speed. In combined turbine, the Savonius buckets are always attached at the rotor shaft and the Darrieus blades are installed far from the shaft which have arm attaching to the shaft. A simple combined turbine offers two rotors on the same shaft. The combined turbine that consists of two Darrieus and Savonius blades was tested in wind tunnel test section with constant wind velocity and its performance was assessed in terms of power and torque coefficients. The study gives the effect of the radius ratio between Savonius and Darrieus rotor on the performance of the turbine. The results show that there is a significant influence on the turbine performance if the radius ratio was changed.

“…The overlap ratio is ratio of the overlap distance (the distance by which the inner edge of the blade overlaps the inner edge of the adjacent blade) by the diameter of the entire turbine. As shown below in figure (Al-Kayiem et al, 2016).…”

“…S-Rotors are also employed at places with low wind potential and where HAWTs cannot run. Since the C p (Power Coefficient) of an S-Rotor is poor in large wind turbines, design parameters are altered as to improve the power coefficient by reducing the size of the rotor itself (Al-Kayiem, Bhayo, & Assadi, 2016).…”

Energy extraction from flowing water has become very prevalent in the twenty-first century. This work aims to harness the power of flowing water to generate hydrokinetic energy. The numerous turbines were used to gather energy from flowing water and were inspired by wind turbines. One of the most common machines is the Savonius rotor. A laboratory-scale model of a Savonius rotor was produced in this work, and the rotor's performance was tested experimentally using a flow diverting blocking plate. The flow behavior and performance of a blocking plate with complete water flow diversion from a retarding vane are examined in detail in this research.
